What is the proportion of thunderstorm climate in Urumqi in a year? Do internet cafes need to press lightning rods?
No installation is required. If your Internet cafe is located in a residential area or a busy area, you don't need to install lightning rods. Generally speaking, larger buildings will have drainage devices. And the lightning protection range is very wide. There is little thunderstorm climate in Urumqi, usually with more rain and less thunder ratio. If your Internet cafe is opened in an open place (it is estimated that this is impossible), I suggest you install it.
